Following a number of delays, the Mozilla Project has confirmed that it plans to ship the seventh beta for version 4 of its open source Firefox web browser on Wednesday, the 10th of November. This seventh beta for version 4 of Firefox 4 is the first beta to include the new Jaegermonkey javascript engine for Firefox.

According to Mozilla Vice President of Products Jay Sullivan, the latest development version includes a number of important performance improvements, helping pages load even faster than in previous beta versions and in the current stable 3.6.x branch.
